For six, my daughter wanted rock climbing, so that is what we did. Most of the places in bay area limit the # and don't have party room.Twisters in Los Altos is where we had it.
The invites was a series of picture cards detailing the party. The top card was a picture of my daughter with the person she was inviting (you and me), then the cards went like this...
map (with route from main highway highlighted)
pants & shoes,
calendar w/date highlighted
clock with start time
rock wall (activity)
bowls of food (snacks)
cake w/candles
clock with end time
then a card had all the info for the non-picture oriented parents.
I put all the cards on a carabener clip that had an O-ring, which slipped over a water bottle. I made a new label for the water bottle (it was a picture of my daughter inverted on a rock wall, I put the place, date, and time around the picture. Where ingredients would go, I put "You, me, and ton of fun!")
They climbed for hours. On the tables I had these magnetic rocks they could build with while they snacked or waited to get back on the wall.
Party favors were little canvas draw string bags (Oriental Trading co.) that look like chalk bags fill with rock oriented stuff- rock candy, pop rocks, geode (no opened), and a soothing rock with a message carved into it (friendship, love, peace, kindness,etc.)
For 5 we did stick ponies- I cut the heads out of wood and bought dowel rods. They decorated them with foam stickers from Michaels. I made up certificates of ownership and when were done decorating and given their pony a name I put the pony's name on the certificiate. Then they had stick pony races-Pony Express- rode around a path avoiding rattles (parents and older kids with dance ribbons) snakes. They had a parade and everyone one a prize - best name, best mane, best gallop, best cantor, best....
This year, 7, we did Rock Video. The girls broke up into groups, headed off into different parts of the house to select a song from a cd (each group was decided by the artist/cd they wanted to do), they practiced words and movements. Then all regrouped and they karaoked while I video taped. I downloaded the video to dvd and mailed it with thank you notes.
I better start planning for 8. It's only 6 mo. away. LOL.
